Product page SEO: the fields that actually move rankings

Most product page SEO advice is a checklist of every field your platform offers, in no particular order, with no indication of which ones matter. This is the shorter version: the things that reliably change rankings and click-through, in the order worth doing them.

Start with the description, because it is usually the problem

The most common ranking problem in ecommerce is not technical. It is that the product description is the manufacturer’s, and so is everyone else’s.

When two hundred retailers publish identical supplier copy, none of those pages contains anything the others do not. There is no reason for a search engine to prefer yours, so it falls back on other signals, which usually means the biggest brand wins by default.

You do not have to rewrite your entire catalogue. Rewrite the products that matter, and write about what the supplier does not:

• Who it suits and who it does not. Genuinely useful, and nobody else says it.
• What buyers actually ask you. Your support inbox is a keyword research tool. The questions that come up repeatedly belong on the page.
• How it compares to the obvious alternative. Including yours.
• Practical details. What is in the box, what else you need, how long delivery takes, what the return terms really are.

The test for whether a description is doing its job: would someone reading it still need to go back to search to answer a question? If yes, that question belongs on the page.

Write the title tag for the click, not the crawler

Title tags in ecommerce tend to fail in one of two directions. Either they are just the product name, which wastes the space, or they are stuffed with every keyword anyone might type, which reads badly and gets rewritten by Google anyway.

A pattern that works across most catalogues:

Brand + Product + the one qualifier buyers search on

The qualifier is whatever distinguishes this variant in a buyer’s mind: capacity, size, material, compatibility, model year. It is the word they would add to narrow their search.

Keep it under roughly sixty characters so it does not get truncated. Do not add your store name unless the store name is the reason people buy, in which case put it at the end.

Meta descriptions do not directly affect rankings, but they do affect whether anyone clicks. Use the space for the thing that actually decides it: free delivery, in stock, the warranty, the price bracket.

Fill in the structured data that has a purpose

Product schema is worth doing properly because it can put price, availability and rating directly into the search result, which visibly changes click-through.

The fields worth getting right:

• name, image, description as the basics.
• offers with price, priceCurrency and availability. Availability matters most, because a result showing “in stock” beats one that does not say.
• aggregateRating and review, but only from real reviews you actually collected. Marking up ratings you do not have is a policy violation and the penalty is losing rich results entirely.
• brand, sku, gtin where you have them. These help search engines match your product to the same product elsewhere, which is how comparison surfaces work.

What is not worth agonising over: the long tail of optional properties. Filling in twenty fields does not beat filling in eight accurate ones.

The one rule that matters more than the field list: the markup must match what a visitor sees on the page. Marked-up prices that differ from displayed prices are the fastest way to lose rich results.

Images: name them and describe them

Product images drive real traffic through image search, and they are usually the most neglected part of the page.

• Filenames should describe the product, not IMG_4471.jpg.
• Alt text should describe the image, for the person using a screen reader first and the search engine second. “Blue enamel cast iron casserole, lid off, showing interior” is useful. “Blue casserole buy online best price” is not.
• Compress them. Product pages are usually the heaviest on the site, and image weight is the usual reason.
• Show the variants. If colour changes the product, show each colour.

Handle stock status without throwing away rankings

An out-of-stock product page has accumulated links, rankings and history. Deleting it discards all of that.

• Temporarily out of stock: keep the page, mark availability accurately in the schema, and say when it is expected back. Offer an alternative on the page.
• Discontinued, with a successor: redirect to the successor. That passes on most of what the old page earned.
• Discontinued, no successor: redirect to the parent category rather than letting it 404. Somebody searching for the old product is still a customer.

Whichever you choose, do it deliberately. Products silently vanishing when stock hits zero is a slow leak that is very hard to notice.

Do not let variants become duplicates

If every size and colour generates its own URL with near-identical content, you have turned one product into thirty competing pages.

Pick one canonical product page and point the variants at it, or use one page with variant selection that does not change the URL. Either works. What does not work is thirty indexable near-copies, which spread your internal links and leave search engines choosing between them.

This is the same failure mode as faceted navigation, at product level. The faceted navigation guide covers the category version, which is usually larger and more expensive.

The order to do it in

If you have a large catalogue and limited time, sequence matters more than completeness:

1. Find your top pages by revenue and by impressions. Usually a small fraction of the catalogue.
2. Fix descriptions on those first. Unique content on your best products beats thin content everywhere.
3. Fix titles across the catalogue. This is usually templatable, so it is cheap per page.
4. Get Product schema right sitewide. Also templatable, also cheap.
5. Work through images on the pages that already get traffic.
6. Then, and only then, work down the long tail.

Working in that order means the effort lands on pages that already have visibility to gain from it, rather than on products nobody has ever searched for.
